The Rail Gun

The US Navy has unveiled a new weapon capable of firing projectiles through 3 reinforced concrete walls at 7 times the speed of sound. Known as The Rail Gun, it has been designed to take out incoming missiles and aircraft.

The standard US surface to air missile costs somewhere north of a few hundred thousand dollars where as each Railgun projectile only costs $25,000. It’s purely electromagnetic, this means there’s no gun powder needed. It launches projectiles over 2,000 meters a second at a range of 160km (100 miles). The bullet is simply a massive piece of metal, accelerated to a ridiculous speed. This speed gives it an incredible amount of kinetic energy which will destroy anything in it’s path.
